Hmmm..... wonder which tuner does this :tsk: and gets away with it!!! :wallbang:johnbanks said:Some tuners do a remap and leave you with standard ignition and valve timing with insignificant changes to the fuelling and fit a boost controller for example. On the Evo making power is very easy so they get away with what is really less than half a job. Quality varies widely.
Some aftermarket IX maps look considerably worse for ignition timing and valve timing than a stock 360, they just run more boost.
